A sequence for distributing at least one of a plurality of code packages to the at least one facility according to different states of a fixed state machine is set. The at least one of the plurality of code packages is installed in at least one staging area. The at least one of the plurality of code packages is maintained in the at least one staging area in a valid, dormant mode while the fixed state machine is stopped. Pursuant to a resumption of the fixed state machine at a subsequent time, a current code package is swapped with the at least one of the plurality of code packages in the at least one staging area to activate the at least one of the plurality of code packages.

Updating elements in data storage facility using predefined state machine over extended time period

Various embodiments for providing an update to at least one storage facility in a computing storage environment are provided. In one embodiment, media is received in one or more updatable elements of one or more components of the at least one storage facility, each of the one or more updatable elements including one or more unique update images and one or more unique update commands, a security verification is performed on the update via a certificate authentication mechanism to confirm a validity of the update, a safety verification is performed on the update to confirm a suitability of the update to the at least one storage facility, the update is installed in the at least one storage facility, and the update in the at least one storage facility is processed by traversing a fixed state machine for each updatable element.

Unattended code update of storage facility

A method for managing persistent data in a multi-image code load system is disclosed. In one embodiment, such a method includes providing first and second code images for loading onto a computing system. The method stores, in a common repository, persistent data that is shared by each of the first and second code images. When changes are made to the shared persistent data associated with the first and second code images, the changes are recorded in the form of content deltas. When generating such content deltas, the method determines which of the first and second code images the content deltas apply to and marks the content deltas accordingly. A corresponding apparatus and computer program product are also disclosed and claimed herein.

Persistent data management in multi-image code load systems

Various embodiments for automated error recovery in a computing storage environment by a processor device are provided. In one embodiment, pursuant to performing one of creating a new and rebuilding an existing logical partition (LPAR) operable in the computing storage environment by a hardware management console (HMC) in communication with the LPAR, at least one failure scenario is evaluated by identifying error code. If a failure is caused by an operation of the HMC and a malfunction of a current network connection, a cleanup operation is performed on at least a portion of a current HMC configuration, an alternative network connection to the current network connection is made, and a retry operation is performed.

LPAR creation and repair for automated error recovery

Various embodiments for providing an update to at least one storage facility in a computing storage environment are provided. In one embodiment, a security verification is performed on the update via a certificate authentication mechanism to confirm a validity of the update. Subsequent to confirming the validity of the update, a safety verification on the update is performed to confirm a suitability of the update to the at least one storage facility. If the security and safety verifications are validated, the update is provided and installed in the at least one storage facility.
